To all whom it may coowcm Be it known that I, EUGENE SCHNEIDER, a citizen of the Republic of France, and a resident of Paris, France, have invented a new and useful Improvement in Removable Bogies for Trailers, Gun- Carriages, and other Apparatus, which invention is fully set forth in the following specification.

In my application Serial No. 183,595, filed July 80, 1917, for improvement in bogies for trailers, gun carriages and the like, of which the present application is a division, I have described a bogie construction capable of being adapted to any desired carriage framing, such as a trailer or gun carriage the variable number of bogies constituting as many elastic suspension devices.

The characteristic feature of the improved bogies is that the bogie axle is connected at its center by a ball-and-socket joint or a horizontal pin to a member constituting the lower abutment, and it may be also the guide, for an elastic suspension, the upper abutment of which is constituted by one of the essential elements of a screw-j ack or like device, which is pivoted about a vertical axis by means of the support of the other element of the screw-jack .or by the actual frame of the screw-jack in the carriage framing.

This arrangement is such that, on operating the screw-jacks in one direction, the carriage framing may be lowered to rest on the ground in firing position and by continuing the operation the bogies may be lifted off the ground. By reversing the operation, the bogies may be lowered to the ground and by continuing the operation the framing may be lifted into traveling position off the ground. The bearing of the wheels upon the ground is assured whatever the contour of the surface during travel.

In order that the invention may be more readily understood, reference is had to the accompanying drawings which show. one constructional form of the invention.

Figure 1 is a front elevational view, partly in section, showing a bogie construction embodying my improvements.

Figs. 2 and 3 are views similar to Fig. 1 showing the parts in different positions.

Fig. 4 is a cross-sectional detail view on the line 4-4 of Fig. 1.

Referring to the drawings, A, A-are the wheels of a bogie mounted 011 the ends of an axle B. I is a part of the carriage framing on which is mounted a supporting collar M comprising an element fast to the carriage framing and a complementary element adapted to be hinged to the fixed element by pins m. The collar is adapted to revolubly receive a screw-jack casing Gr by removing one of the pins on and opening the hinged element of the collar. K is a threaded element of a screw-jack revolubly mounted in the top of the casing G and is provided with a polygonal head for receiving a wrench handle L. V

E is an elastic suspension device prefer ably consisting of a pile of Belleville washers which are confined between a nut F of the screw-jack and the bottom d of a socket or barrel D which latter is adapted to slide inscrew-jack casing G. The lower end of the wall of barrel D is extended in the form of two cheeks D (Fig. 1) which straddle the axle B and are pivotally connected therewith by a pin G In order to limit the pivotal movements of the axle B there is provided a member D adapted to be screwed or fixed to the socket or barrel D or simply held between the axle andcheeks D. For a like purpose a collar D may be secured on the ends of the cheeks D Rotational movement of thenut F is prevented by a rib F thereon guided in a slot D in socket D.

Assuming the parts of the screw jack bogie are in the position shown in Fig. 1, the framing I can be raised or lowered rela tively to the ground within determined limits.

For this purpose it is merely necessary to operate the screw member K by meansof lever L. According to the direction of movement of this lever the framing will be caused torise or to descend. In the latter case the gun carriage to which the screwjack bogies are pivoted can be lowered to the position shown in Fig. 2 so as to bear upon the ground. Then by continuing to operate the lever L nut F rises 011 threaded member K against inner collar d thereby lifting barrel D and with the latter wheels A into a position off the ground'as shown'in Fig. 3. By a reverse rotation of lever L the wheels A may be lowered to the ground and framing 1 elevated into transporting position off the ground.

What is claimed is:

1. In a bogie for supporting a trailer, gun carriage or other vehicle, the combination of a wheeled axle, a spring barrel pivotally mounted on said axle, a vehicle frame, a tubular member revolubly mounted thereon and adapted to receive said barrel, a thread- 7 ed rod revolubly supported in said tubular member and provided with a nut movable into lifting engagement with said barrel and a suspension spring in said barrel having said nut as one abutment and the end of said barrel as the opposite abutment.

2. In a bogie for supporting a trailer, gun carriage or other vehicle, the combination of a wheeled axle, a spring barrel pivotally nut having a splined connection with said barrel and movable into lifting engagement with said barrel and a suspension spring in said barrel having said nut as one abutment and the end of said barrel as the opposite abutment.

In testimony whereof I have signed thisspecification.
